To all whom it may concern:

Be it known that I, UUNO E. TUoMI,,a citizen of the United States, andresident of St., Louis, Missouri, have invented certain new and usefulImprovements in Mechanism for Operating Window-Sash, of which thefollowing is a specification. I

This invention relates to improvements in a mechanism for operatingwindow sash, and it consists in the novel arrangement, construction andcombination of parts, the detail of construction will be hereinafterfully described and set forth in the claims.

The object of my invention is to construct a mechanism which isconcealed in the window frame which supports a plurality of window sash,and by said mechanism any one or plurality of the sash canbe opened bythe manipulation of the mechanism, from a position in close dow sill.

Another object of my invention is to equip the frame with a means bywhich any one or a number of the sash may be placed in and out ofoperation so that by the manipulation of the opening mechanism acertainnumber of the sash will open while the others will remain closed.a

This structure is adapted for windows which are hingedat the top andopen in a swinging manner. The structure in additionto the operating ofthe sash also acts as a complete lock to prevent the windows from beingopened from outside, and the general construction of the sash frame isso arranged as to make an absolute leak-proof joint when the windows arein closed position.

The device although comprising considerable mechanism and from theappearance of the parts as illustrated on the drawing seems to becomplicated yet the device is comparatively simple and operative inevery respect for the purpose it is' intended.

I In the construction of my invention I provide a suitable window casingor frame 13, which is provided with division posts 14 dividing the frameinto several sections in which are hingedly mounted a plurality ofwindow sash 15.

At thebottom of the window frame or casing is provided a suitable box 16in which is located and supported the general operating mechanism 17.This mechanism consists of a horizontal shaft 18, supported in suitablebearings 19 and on the shaft are provided a plurality of beveledgearwheels 20, which are arranged in mesh with beveled pinions 21,firmly attached to vertical screw-threaded shafts 22. These shafts.extend in the frame from the bottom to the top, its upper end seated ina bearing 23 and the shafts are properly located in rectangular recesses24, formed in the side walls 25 of the casing.

On the shaft 18 is likewise provided a beveled gear 26, keyed to theshaft 18 and a I B 'thefrnanipulationof thecrank 30 this .rnec anisinplacesallfjof the vertical screwthreaded'shafts 22 in'simultaneousrotation.

Against-the frame" andmin approximate alinernentwith the lowerend 31 ofthe window sash 1 5, aresecuredbrackets 32 which are arrangedto receivethe threaded shafts 22 and actas a stop' for the-sash operatingmechanism-, which-mechanism.consists of ahollow "boxflmemberfl-33, whichis provided witha projecting ear34; in which is a peri 7 foration35;Throughjthis perforation is inserted a rivet'orgboltyconnecting to thebox an operatingarm 536,".thefopposite end of smaller diameter, thelower edge :39 beingwhich is pivotally attached to, the side'of thewindow sash, and by this arm the sash is. opened -andblosed by themanipulation of the mechanism.

Onv the s'ha 22 are provided internally screw threaded nuts 37 which arerectanguv lar in form, the bottom portion38 being of beveled inwardly soas toact as a'proper guide when the nut 37 is to enter into the. hollowbox 33. This bottom portion 38 is provided with a receiving recess 40which is shaped with a rounded portion 41 and an elongated portion 42,and recess is designed to properly come into alinement with the opening'43 formed in the box and in which is supported a controlling plug 44,(see Fig. 9). This plug consists of a central rounded bearing portion.45, in its inner end terminating into a rectangular portion 46 and itsouter end terminating into a rectangular portion 47, but arranged in anopposite position to the projection 46. The part 46 is inserted throughthe opening-.43 by slightly tilting the plug and allowing it to passthrough the diagonal elongation 48, and

then allow the bearing portion 45 to properly seat itself through therounded portion of the bearing. The recess 24 in the frame in which thescrew-threaded shafts 22 are located is of such size as to properlypermit the box and nuts to ride up and down on the shaft but yet preventthe same from binding during its upward and downwardmotion. 1

Against the frame and slightly above the brackets 32 are fastenedbearings, 49 which properly support the key shafts 50 by which the plugs47 are manipulated.. These keyshafts are provided with a slotted end 51which are arranged in proper alinement with the plugs when the boxes 33are resting upon the brackets 32. The front end of the key shafts aremade rectangular in form as indicated by the numeral 52 and of the plug.The general position of the I parts is shown in'Fig. 7. 1

As this mechanism is one of the important features of the invention Iwill now describe the operation of the same.

By referringto' Fig. 7, the nut is in a position to be elevated by theturning of the screw-threaded shaft without in any way- 'operatingthewindow sash and on account of the vertical position of the end 46 of theplugit will permit the nut 37 to ride upwardly'and pass the end 46bymeans of the elongated portion 42"of the recess. When this nut is sopassin out the box 33 will remain in position being held in that mannerby the plug and key shaft.

.-When it is desired to operate the sash in order toopen the same, thekey shaft 50 is turned to bring the end 46 of the plugin horizontalposition. .This will place that end in. a rounded portion 41 of therecess andbe located therein as shown in Fig. 6. The opposite end ofthe. plug being vertical which when in this position the rotation of thethreaded shafts will cause the nut and the box to ride together on theshaft and in so doing willexert ressure on the sashoperating arms v36causing the sash to swing out from a vertical to a tilted position asthat shown in Fig. 3.

In order to properly manipulate the upper windows from the bottom of theframe I place on the front of the partitions 14, a

plate 54 which supports aplurality of key shafts 50, thebottom twocontrolling the bottom nuts, the center two controlling the center nutsand the upper two the upper nuts. The upperandcenter seriesof key shaftsas supported in the plate54, are not provided with the slotted innerends but merely have hearing so that the key shaft which is in alinementwith the nuts on the center and upper series of the window sash aremanipulated.

In order to manipulate the key shafts in the upper part of the frame Iprovide on the shafts a cross-bar 55 to which are attached rods or wires56 and whenthe lower key shaft is turned it operates the upper key shaftin unison. The cross-bar on the lower shaft is provided with aprojection 57 which operates in a curved slot 58 formed in the platewhich is marked on and off, the projection 57 acting as indicator orpointer to show how the nuts are turned so as to open the window orleave it closed,

-it is desired to remove through the opening .63

incense.

Ey this arrangement the operator by the manipulation of the crank 30 thespecified windows will beopened. The general mechanism in the frame isconcealed by placing over the same strips as that shown in theillustration.

The lower set of key shafts are held in frictional contact by means ofthe spring 59 which is for the purpose to hold the shaft so that theslot will remain in vertical alinement so that the end 47 of the plugwill properly seat itself therein when the nut and box is brought backto its normal lowered position. 1 lin Fig. 12, I show a pivot hinge bywhich each of the sash are hingedly mounted in position in the frame. vof a plate 60 embedded in the casing, the same being provided with a pin61 which freely operates in the opening. Saidpin having a bore on itsupper end through which is passed a spring 62, the opposite end of thespring being held in rigid connection-with the plate and frame and whenthe sash from the hinge an instrument or tool is inserted formed intheplate, and brought in contact with the spring 62 thereby pressing thepin 61 rearwardly so as to release it from the openingtii formed in thehinge plate 65 laid flush in the sides of the window sash.

Theconnecting edges of the window mesh with one another and with theframe or cas ing and are so arranged as to make an absolute water anddust-proof joint. This general arrangement is clearly illustrated inFigs. 3 and 4.
